tests: Prepare distro images during asset build phase Before booting the guest images, the distro test cases need to modify the guest images, using virt-edit and guestfish, to boot in the way we need. At present this gets repeated on every test run, even though it's not really doing anything we want to test for. In addition many of the images have the same preparation steps leading to a lot of duplicated stages in the tests. A number of additional images can be prepared using common steps, even if the ones used now have small differences. Therefore move the preparation of most of the guest images to the asset build phase, where they can be done a single time for multiple test runs, using a common preparation script. We can even avoid making a copy of the disk image for booting, by using qemu's -snapshot option. A few of the distros (openSUSE and older Ubuntu) do need different steps. For now we don't chage how they are run, they could possibly be handled more like this in future. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

Makefile: Ugly hack to get a "plain" Markdown version of README Distribution packages reasonably expect to have a human-readable Markdown version of the README under /usr/share/doc/, but all we have right now is a heavily web-oriented version. Introduce a ugly hack to strip web-oriented parts from the current README and install it. It should probably work the other way around: a human-readable README could be used as a source for the web page. But cgit needs a file that's in the tree, not something that can be built, and https://passt.top/ is based on cgit. It should eventually be doable to work around this in cgit, instead.

test: Avoid hitting guestfish command length limits In test/prepare-distro-img.sh we use guestfish to tweak our distro guest images to be suitable. Part of this is using a 'copy-in' directive to copy in the source files for passt itself. Currently we copy in all the files with a single 'copy-in', since it allows listing multiple files. However it turns out that the number of arguments it can accept is fairly limited and our current list of files is already very close to that limit. Instead, expand our list of files to one copy-in per file, avoiding that limitation. This isn't much slower, because all the commands still run in a single invocation of guestfish itself.
